processing brain

Hello everyone,
I was just wondering if anyone could give suggestions on how long to
process new born pig brain. It is not the whole brain at once, just
cherry sized pieces. My processor is a Shandon Citadel 2000, and the
stations are 70%EtOH, 95%, 95%, 100%, 100%, 100%, 3x xylene, and 2x
paraffin with the last paraffin having a vaccuum. Thank you for any
suggestions.
